G25 Shifter damaged

I have the Logitech G25 wheel.
After playing a lot GT Legends with H-shifter, my sequential shifter does not work properly anymore. Sometimes only I slight touch moves 2-3 gears which is really annoying.

I don't have warranty anymore so to repair it is not worth it I think.

Had somebody similar issues and could repair it.
Otherwise what are the alternatives ?
maybe a single sequential shifter ?

If you want a new H pattern, these are apparently very good. You could still use your G25 gearbox for sequential and all the buttons. If you ever need a new sequential, the only one I can think of is the Frex one and it isn't cheap.
